With use of 2.00 g of 2-bromomethylaziridine hydrobromide (2) obtained in the above Example 1, there was produced a solution of 1-azabicyclo[1.1.0]butane (4) dissolved in tetrahydrofuran by the same method as in the above Example 7. Next, to a 5 ml solution of dried tetrahydrofuran containing 1.32 ml of thioacetic acid, there was added dropwise a solution of compound (4) dissolved in tetrahydrofuran at a temperature of -40° C. or lower, and the resulting mixture was stirred at a room temperature for 18 hours. After the reaction was over, the solvent was distilled off, and the residue was separated and purified by silica gel column chromatography (eluent: chloroform-acetone), and, thus, there was obtained 828 mg (yield: 51.8%) of 1-acetyl-3-acetylthioazetidine (11).
